    Best Practices for Extending UHF Radio Range The UHF radio in the iG9 has excellent range. However, range is greatly reduced by other users on the same frequency, damaged antennas, damaged cables and configuration issues. The most common range issues are listed below. If you need to dependably operate at more than 3- miles from your Base, consider purchasing a repeater.
